Both types have similar properties, but stem bromelain is more commonly used in supplements due to its higher enzyme concentration.
1.2. Historical Uses
Historically, bromelain has been used for:
- Treating inflammation
- Reducing swelling
- Healing wounds
- Improving digestion
Indigenous populations in South and Central America have long used pineapple for its medicinal properties.
1.3. Chemical Composition
Bromelain is a complex mixture of different thiol endopeptidases and other components like:
- Phosphatase
- Glucosidase
- Peroxidase
